The Soap Factory at 111 Gallowgate, Aberdeen, Scotland, was built for Ogston & Tennant, soap and candle manufacturers, in 1922. The building was designed to be the formal office and to stand detached from the main factory and warehouses, which opened onto Loch Street. Ogston & Tennant ceased trading in the 1970s, and the building is now used as offices. It is a category C listed building.
